Features:
Butterfly valve, is a simple structure of the control valve, can be used for the low pressure pipeline medium switch control of butterfly valve is to close the disc, rotating around the valve shaft to achieve the opening and closing of a valve.
Valves can be used to control the flow of air, water, steam, corrosive media, mud, oil, and other types of fluid. It is mainly used for cutting and throttling in pipelines. Butterfly valve opening and closing parts is a disc shaped disc, in the valve body around its own axis rotation, so as to achieve the purpose of opening and closing or regulation.
1. Small and light , and easy installation and maintenance. It can be mounted wherever needed.
2. Compact structure, 90 degree fast switch.
3. Min operating torque, energy saving.
4. Flow curve tending to straight line. Excellent regulation performance.
5. Long service life Standing the test of tens of thousands opening/closing operations.
6. Bubbles-tight sealing with no leakage under the pressure test.
7. Wide selection of materials, applicable for various medium.
